Abstract

Abstract This paper investigates the behavior of a new form of V-shaped shear connector. The assessment of the proposed connector’s performance is conducted through an experimental work of fourteen push-out tests. The results show that the developed V-shaped shear connector is able to transfer higher shear load than the conventional shear connectors. In addition, its behavior is considered as ductile. Geometrical parameters of the connector are studied to observe their influence on its behavior. The experimental outcomes show that changing the length, width, and thickness of the connector significantly affects its ultimate strength while the connector's ductile behavior is preserved. Furthermore, the work proves that neither creating holes nor adding transverse reinforcement to the connector has significant effect on shear resistance and that the uplift-displacement of the connector is improved. A comprehensive comparison between the proposed shear connector and commonly used shear connectors is executed. Based on the experimental results, an empirical equation is suggested to predict the load capacity of the connector.
新型弯曲V型剪切连接件的试验研究
摘要本文研究了一种新型V形剪切连接件的性能。通过14次推出试验的实验工作,对所提出的连接器的性能进行了评估。结果表明,所研制的V型剪切连接件能够传递比传统剪切连接件更高的剪切载荷。此外,它的行为被认为是韧性的。研究了连接器的几何参数,以观察它们对其性能的影响。实验结果表明,在保持连接件韧性的同时,改变连接件的长度、宽度和厚度会显著影响其极限强度。此外,研究证明,无论是开孔还是在连接件上添加横向钢筋,都不会对抗剪性能产生显著影响,并且连接件的上拔位移得到了改善。对所提出的抗剪连接件和常用的抗剪连接器进行了全面的比较。根据试验结果,提出了一个经验方程来预测连接器的承载能力。
